BREEDING-CALENDAR.

SPECIFICATION forming part of Letters Patent No. 351,131, dated October19, 1886.

Application Filed July 2. 1886. Serial No. 206,933. (No model.)

To all whont it nto/,y concern.-

Be it known that l, JOHN VV'. SN'IDER, of Fairland, in the county ofShelby and State of Indiana, have invented a new and ImprovedBreeding-Calendar, of which the following is a full, clear, and exactdescription.

rIhe object of the invention is to furnish a calendar having attachedadjustable disks for indicating the period of parturition or time youngwill or should be brought forth, the date of copulation or conceptionbeing known.

The invention is applicable to animals of all kinds, also to thehatching of the eggs of poultry or birds oi' different kinds, dto.; andit consists in a calendar of novel description, including certainconstructions and combinations of parts, substantially as herein shownand described, and whereby the calendar may not only be used .as achangeable or perpetual one for ordinary reference purposes, but as aspecial one for breeding purposes, as above described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the gures.

Figure l represents a partlybroken front or face view of a calendarhaving my invention applied. Fig. 2 is a rear view of the same, and Fig.3 a longitudinal section thereof upon the line .fr in Fig. l.

A indicates the main body, which may be composed of an oblong piece ofcard-board or other suitable material with an aperture, b, in it at ornear its one end, or otherwise suitably disposed. Down or along one sideofthe face of the body A are two tables or strips, B G, the one ofwhich, B, that is xed has the names or abbreviations of the days of theweek extending over a period of five weeks and two days printed orotherwise exposed in succession upon it. The other of said strips, C,that is arranged along the side of the fixed strip B, has the number ofdays (thirty-one) in the longest months of the year exhibited insuccession from l to 3l upon it. The last strip, C, ismade capableofbeing slid up and down, as through staples c or other suitablefastenings, which may also serve to hold both strips to their places. Bymeans of the sliding ofstrip G, which is a date one, it maybe adjustedin such variable relation to theindicatio ns on the Xed strip B as togive the day of the week upon which the first or any particular date ofany month falls in any year. To aid the setting of this strip C a table,D, showing the rst ofthe month for twelve months during one or moreyears. may be secured on the face of the body A. The names of months areexposable in succession by suitably turning an adjustable or rotatabledisk, E, having the several months of the year arranged in succession atequal distances apart around the marginal portieri ot' its face, sofasto exhibit the month through the aperture b in the body. rlhis may besaid to complete the calendar for general use, and is also serviceablefor indicating dates or days Vof the'week in any particular month of anyyear when a breeding record or calculation has to be made. D

To adapt the calendar for use in connection with the breeding of stock,l elect to use two rotatable monthly calendars or disks, though for asingle stock a single disk having two circular rows of months, the oneexpressing the period of copulation or conception and the other theperiod of parturition or birth. substantially as hereinafter describedfor two disks, might be used.

The disk or monthly calendar E forms one of the pair o'fdisks and asmaller disk, F, the other one of said pair. The disk F, which isarranged upon the face of the disk E, has the several months of the yeardisposed on and around its face, as in the case of the disk E, so thatit also forms a monthly calendar. These two disks are concentric inrelation with each other and are fitted to turn both independently andcollectively upon a single eyelet, rivet, or pivot, d, which securesthem upon the back of the body A. Said disks are or may be made ofcardboard or any suitable material, and the rearmost disk, E, be clampedby bending over a portion, e, of the body A cut, but not removed, whenmaking the aperture 7),' but this clamp or clip e does not prevent therotary movement of the disk E.

The names of the months, or abbreviations thereof upon the face of thedisk F, are covered from exposure through the aperture b, when required,bya movable screen or blind7 G, which may be pivoted on. the face of theIOO body A at the same center as the disks E and F. By turning the blindor shutter toone side, as shown in Fig. 1, then some one of the seriesof monthly indications upon the face of the disk F is exposed in commonwith a monthly f'indication upon the disk E through the aperture b. p

rIhe disk E has aperturesf in it arrangedin radial relai-ion to themonths lmarked upon the face of said disk and within the range ordiameter of the disk F, and opposite these slots or aperturesf areprinted or inscribed the names ofthe different animals, Sto., itisrequired to use the breedingcalendar for. Upon the back of the disk Fis a stud or pin, g, which, by a suitable circular adjustment of thedisks and flat position of the disk E upon the disk F, is free to engagewith some one of the apertures f in the disk E, whereby the rotation ofthe two disks in common is practicalble; but upon slightly raising themarginal portion of the disk E opposite the clampe. which is readilydone by constructing the disk E of suitable flexible or elast-icmaterialsuch `as card-board--then the pin g may be disengaged from theaperture f it was entered within, and the two disks E and F be atliberty to be` independently rotated or adjusted, or the disk E only berotated, while the disk F remains stationary. A convenient means forthus engaging and disengaging the two disks consists in a simple slide,H, formed of a strip( of metal or piece of wire bent upon itself, withafork, t, at its inner end and having a wedge-shaped projection, k, atthe root of the fork. This slide is arranged on back of the body A',over a lower strip, I, of cardboard or other suitable material fastenedon the body A, butleft free at its upper end to overlap the lowermarginal port-ion of the disk F. Said slide H is made capable of beingmoved up or down through staples or guides l,

which staples or guides secure the slide to or on the back of the body Aor strip I thereon.

Supposing the disks E and F to be engaged with one another, asdescribed, and the pin g to be in an aperture, f, directly over and inline with the slide H, as shown in Fig. 2, then by pushing the slideinward or upward the projection k on said slide will lift the disk Efrom engagement with the pin g of the disk F, and the iork t willstraddle the pin g, to hold the disk F stationary, while the disk E isturned or set for any particular kind of stock,

as indicated by the inscriptions on the back of said disk opposite theapertures if. Upon drawing down or back the slide H the pin g ill beentered within the aperture f, brought in position for the purpose asdescribed, and

two disks E and F will be engaged with another by the return flexingaction of the V E as the projection k is moved from Aunand the fork t'will be relieved from its f the disk F by its pin g, and the two d I befree to rotate in common again-as,

! instance, by applying the finger to the marginal portion of the diskEkopposite a cutaway portion, m, in the side of the body A.

The strip I, while it does not restrain .the rotary movement of the diskF, serves as a guide for the slide H when moving the slide inward tolil't the disk E, and to engage it by its fork with the pin g, andprevents said slide, when thus moved, from' catching against or passingunder the disk F.

The larger disk,r E, 1s the one used for indicating the period ofcopulation, or supposed' conception, and the smaller disk, F, theone forshowing the probable or approximate period of p'arturition or birth.These disksmay only give the periods of gestation in months fordifferent kinds of stock, and the exact date may be ascertained byadding or subtracting I apertures f, are so arranged that whenever theengaging pin g is entered within the aperture f opposite acertain kindot stock, and the two disks turned in common to expose th rough theopening b the month of copulation or conception on the larger disk, themonth or period ot parturition or birthwill be shown immediately beneathit upon the face of the disk F-that is, when the blind or shutter G isturned to one side to expoe it. Thus, to use the calen- 'dar forbreeding purposes, the blind G is turned aside to allow the months ofboth disks to show at the aperture b. The two disks E and F, beingengaged, are then turned till the slot or aperture f, with the pin g init, is opposite the slide H. Said slide is then pushed in till the'disksare separated, afterwhich the disk E is turned till the aperturef,indicative of the particular stock it is desired to expose on thecalendar, is over the pin g of the disk F, held by the fork of theslide. The slide H is then drawn down or out, and the two disks, whichthen become engaged again, are turned in concert till the month ofcopulation on the disk Eis exposed through the aperture b, when theperiod or monthl of parturition shown on the face of the disk F willalso be exposed through the aperture b.

If, for instance, the calendar is set for horsebreeding, which is theillustration shown in the drawings, and supposing copulation to havetaken place in February, then that month will be exposed on the disk E,and January on the disk F, a period of eleven months, which is thenumber of months for gestation of a mare, will be exposed on the disk F;or the engaged disks may be turned to expose on the disk E a differentmonth of copulation, when the period of parturition, showing elevenmonths later, will be exposed on the disk F. A like action takes placewhen using the calendar for the other kinds of stock, only the period ofgestation being changed as exhibited on the iaces of the engaged disksWhere exposed at the opening bin the body. Vhen an exact date isrequired, then the number of days opposite a particular stock, as shown.on the table M, i'or instance, should be added to or substracted fromthe date oi' copulation or conception during the month shown on the diskE, and for xing these dates, both by numbers and the day of the Week,the tables or strips B C will be found convenient to refer to; or theblind G may closed over the exposed portion ot' the disk F through theaperture b, and the disk E be used in connection with the tables B C forgeneral reference, or for any purpose to which a calendar is applicable,as

hereinbet'orc explained.

lt should here be understood that While for the convenience ofdescription the strip or table B ot' Weeks and days is herein referredto as the iixed one, and the strip or table C of dates as the sliding oradjustable one, the order of the Same may be reversed-that is to say,the table B may be the movable one and the table C the fixed one. Suchchange would not affect the result nor the manner in which it isobtained, and I consider such change of said strips or tables as theequivalent of making the table B stationary and table C adjustable, asherein described.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. In a calendar for indicating the periods ofparturition or birth of stock, the date of supposed conception beingknown, the combination ol" a rotatable monthly calendar or disk havingthe names of the stock opposite the months marked upon it, a secondrotatable monthly calendar or disk expressive of the periods ofparturition, and means for engaging and disengaging said disks, andadapted toengage them at different points in their monthly divisions,essentially as and for the purposes herein set forth.

2. In a stock-breeding calendar, the combination, with the body A, ofthe calendar having an exposing-aperture, b, of the rotatable monthlycalendar or disk E, having the names of the stock opposite the monthsmarked upon it, the smaller concentric rotatable monthly calendar ordisk, F, and means for disengaging said disks from each other, andadapted to engage them at different points in their monthly divisions,substantially as specified.

3. In a stock-breeding calendar, the rot-atable monthly calendar or diskE, having aperturesf, and the names of the stock opposite the monthsmarked upon it, in combination With the lesser and concentric rotatablemonthly calendar or disk F, provided with an engaging pin or stud, g,essentially as described.

4. In a stock-breeding calendar, the combination, with the rotatablemonthly calendar or disk E, having aperturesf, and the names of thestock opposite the months marked upon it, and the lesser and concentricrotatable monthly vcalendar or disk F, provided with an engaging pin orstud, g, of the slide H, adapted to litt the disk E from engagement withthe disk F and to hold the latter from turning, substantially as and forthe purposes specified.

5. In a stockbreeding calendar, the combination, with the body A, havingan exposing- Y aperture, b, ofthe rotatable monthly calendar or disk E,having the names of the stock opposite the months marked upon it, thesecond rotatable monthly calendar or disk, F, adapted t0 engage with thedisk E at different points in the monthly divisions on it, theadjustable blind or screen G, the fixed table B ot' Weeks and days, andthe sliding or adjustable table C of dates, substantially as shown anddescribed.
